New energy automobile power battery deep charging and discharging calibration device

Abstract

The invention relates to a new energy automobile power battery deep charging and discharging calibration device, and belongs to the technical field of V2G charging piles, the front end of a calibration device main body is provided with a first connecting column and a second connecting column, the first connecting column is connected with an anti-loosening fixing clamp through a transmission line, a connecting device is inserted into the first connecting column, and the second connecting column is connected with the anti-loosening fixing clamp through a transmission line. The connecting device is connected with the anti-loose fixing clamp through a transmission line, the connecting device rotates around the second connecting column, and one side of the calibration device main body is provided with a storage device for placing a detection part. The method has the beneficial effects that the power battery is deeply charged and discharged once, so that the activity of the battery can be stimulated to the maximum extent, the percentage accuracy of the electric quantity of the battery can be calibrated, the electric quantity of the V2G charging pile for charging the battery is more accurately grasped, and the problem of over-charging or over-discharging of the battery is avoided.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle batteries, in particular to a new energy vehicle power battery deep charge and discharge calibration device. Background technique [0002] With its low emission, high efficiency, and multiple energy sources, electric vehicles have become one of the important ways to solve the current problems of environmental pollution and oil resource shortage. At present, electric vehicle technology is developing rapidly at home and abroad, but the battery as the power source of electric vehicles is the bottleneck of its development. Designing an on-board charger that meets the charging requirements of the power battery can effectively prolong the service life of the battery and keep the electric vehicle at a high driving range for a long time, providing effective support for the practicality and popularization of electric vehicles. [0003] Two-way V2G is the abbreviation of Vehicle-to-grid, which d...

Problems solved by technology

[0005] However, the existing battery charge and discharge calibration equipment has certain disadvantages. First, the battery deep charge and discharge calibration device is connected to the battery through the transmission line and the connecting clip. When the wire on the connecting column is used for a long time or after winding, it is easy to damage or fall off between the wire and the connector, and the detection device is equipped with many auxiliary devices, and there is nowhere to place the auxiliary devices.

[0006] The existing V2G charging piles are not clear enough to detect the battery power. If the V2G charging piles are not sure about the battery charging power, it will happen that the battery charging is not enough for the new energy vehicle to run, and it will stop halfway, which will cause trouble for the people in the car. There will be certain troubles and safety hazards
